Abstract

The occurrence of ferroelectric charged domain walls (CDWs) which was thought to be energetically unstable is observed, together with a ferroelectric vortex structure composed of 109° and 180° domains near an epitaxial BiFeO3/GdScO3 interface. The CDW and vortex affect the domain arrangement, domain configuration, and hence tune the domain size distribution. [ABSTRACT FROM AUTHOR]

Abstract

We reported that the tetragonal-like phase identified in strained epitaxial BiFeO3 films on a (001) LaSrAlO4 single crystal substrates is monoclinic MC, based on high resolution synchrotron x-ray studies and piezoresponse force microscopy measurements. This MC phase has different symmetry with the rhombohedral-like monoclinic MA phase found in BiFeO3 films grown on low mismatch SrTiO3 substrates. Transmission electron microscopy revealed that the films on LaSrAlO4 substrates have a high crystalline quality and coherent interface. [ABSTRACT FROM AUTHOR]
